IMPROVEMENT lN CARBURETERS.

Specification forming part of Letters Patent No. 144,858, datedNovtniber 25, 1873; application filed October 2, 1873.

To all whom it may concern Be it known that I, JAMES MUSGRAVE, ofCincinnati, county of Hamilton and State of Ohio, have invented anImprovement in Gas- Generators, of which the following is aspecification:

My invention relates to that class of gasgenerators in whichilluminating gas may be manufactured by means of impregnating air withthe vapor of naphtha or gasoline.

The generator which I have invented has this advantage over those whichhave preceded it, that it is simple in construction, dispensing, as itdoes, with canvas or other porous material requiring to be renewed, andwith all internal machinery liable to get out of order.

In the drawings, Figure 1 represents an inside view of my improvedgenerator, with sectional views of the pipes through which the airenters and the gas escapes. Fig. 2 is a sectional drawing of the floatand chamber, hereinafter to be described.

In operation, air is forced into the pipe a by means of any suitabledevice. (Not represented in the drawing.) The air passes down, througha, b, c, c, d, and d, into the mixing chamber D, which floats on thesurface of the gasoline, with which the tank T is partly filled. In thebottom of this chamber are a number of openings, e 6, through which theair is forced. Having no other means of escape, the air passes along inbubbles between the surface of the gasoline and the extended bottom ofthe chamber D, with its float attachment F, until it flange H, throughwhich it escapes into the The air first comes in contact with thegasoline vapor in the mixing-chamber D, and there becomes partiallyimpregnated with the same; and as it passes in bubbles over thegasoline, underneath the float, as described, it takes up still morevapor, so that by the time it reaches the perforations g git isthoroughly impregnated. This saturated air, which is ready, or nearlyready, for use as illuminating-gas, collects, as

described, in the upper part of the tank T,

from which it passes into the pipe t through the openings 70 k, and fromt is conveyed, through I and other pipes, as occasion requires, to theplace where it is to be consumed.

In order to reach the openings 76 7c, the gas is obliged to enter adrum, m, which encircles the pipe 2', through a multitude ofperforations in the side or sides of the drum. This serves to regulateor steady the flow of gas from the tank, and also to condense and removefrom the gas superfluous gasoline vapor, if in the process ofmanufacture the air has become too thoroughly saturated. not communicatein any way with the interior of F, that being a hermeticallysealedairchamber fastened around D in order to float it. Around thisair-chamber extends the horizontal flange H, provided with perforations,as shown and described, the object being to secure more perfectimpregnation of the air by keeping it longer in contact with thegasoline before escaping into the body of the tank T. Thismixing-chamber, sealed air-receptacle, and perforated flange,constructed as herein described, or in an equivalent manner, constitutetogether the float, which is the principal feature of my invention. Inorder that this float may freely rise and fall with the varying depth ofgasoline in the tank, the pipes 0 and d are secured to it, to eachother, and to the stationary pipe I) by means of flexible screwjoints,which are hollow to admit of the free passage of air through thepipes,.as described. The pipes c and d are jointed in the same manner.The two elbows formed, respectively, by the pipes c and cl, and by thepipes c and d, project in opposite directions. The two setsof pipes thusbalance each other, and the equilibrium of the float is preserved as itrises and falls.

The pipes a and 42, although they may, as represented, be continuous,are not intended to communicate with each other, except by thecircuitous route already described, and indicated by the arrows in thedrawings. All parts of the gas-generator herein described are or may bemade of metal.

The cistern or tank T, one-half of which is shown in Fig. 1, is intendedto be air-tight; and, as in common use it is buried in the ground forthe sake of protection from sudden changes of temperature, it should bemade of some substance which will not readily corrode or decay in thepresence of moisture. It may be of any desired size, and of any shapecon The chamber D does sistent with the accomplishment of the end forwhich it is designed, as herein described.

1? is the pipe through which the naphtha or gasoline is poured into thetank. Its lower extremity is near the bottom of the tank, and shouldremain constantly beneath the surface of the gasoline therein; and thepipe should be of such a length that, when the tank is buried, its upperextremity may be within easy reach.

I claim as my invention- 1. A mixing chamber, D, and float F, incombination with a perforated flange, H, substantially as and for thepurpose specified.

2. In combination with the mixing-chamber D, float F, and perforateddisk H, pipes con- JAMES MUSGBAVE.
